An EKG checks the electrical signal around the heart and can pick up abnormal heart functions. For example, the ventricles taking too long to contract or relax, or the atria being abnormally fast. Many things can be detected on an EKG and yes the placement of the leads can sometimes give wrong results, which is why they usually do a repeat if something unexpected is seen. To see the actual physical movement of the heart, see the valves and the dimensions of wall thickness, overall heart size etc, you need an Echocardiogram. Then to see the arteries condition you need an angiogram or ct-angio and to back this up there is the possibility for a nuclear scan.
I stop taking cymbalta before 15 days and then took my ECG which gives me abnormal results as said above. I still thinking of my results why it is abnormal?. I also heard that ECG results are NOT 100% accurate. if this YES what test i need to confirm about my heart functionality?
The ST-T changes on the ECG can be a sign for a heart attack. They should have taken blood to test your Troponin level and then repeated that test 12 hours later as confirmation.
I'm not sure what your question is. You apparently have an abnormal EKG. Square two is generally a stress test, either chemically mediated or without, depending on your cardiologist.
